Create a Venn Diagram

ggVennDiagram(toy_sets[1:3])

Choose a different name for each Venn plot

ggVennDiagram(toy_sets[1:3],
              category.names = c("ALICE","BOB","CHARLIE"))

Setting the color for labels for each Venn plots

ggVennDiagram(toy_sets[1:3],
              set_color=c('blue','red','black'),
              category.names = c("ALICE","BOB","CHARLIE"))

Different Venn Plots of Various Sizes

ggVennDiagram(toy_sets[1:2], label='count', label_color = "firebrick")

ggVennDiagram(toy_sets[1:3], label='percent', label_color = "firebrick")

ggVennDiagram(toy_sets[1:4], label='both', label_color = "firebrick")

ggVennDiagram(toy_sets[1:5], label='none')

ggVennDiagram(toy_sets[1:6], label='count')

ggVennDiagram(toy_sets[1:7], label='none')

Setting Edges and color palette and adding note

ggVennDiagram(toy_sets[1:4], edge_lty = "dashed", edge_size = 1) +
  scale_fill_distiller(palette = 'Reds') +
  labs(
    title='How many toys each Person has ?',
    subtitle = 'Plot: Venn Diagram',
    caption = Sys.Date()
  )

Venn Diagram doesn’t support more than 7 Venn plots. We need to use Upset charts to visualize more than 7 data points.

ggVennDiagram(toy_sets[1:2], force_upset = TRUE,
              nintersects = 10, relative_height = 1, relative_width = 0.3)

ggVennDiagram(toy_sets, force_upset = TRUE,
              nintersects = 15, relative_height = 1, relative_width = 0.3)
